Further objects, novel features and relationships will be set out moreclearly in the following description relating to the accompanyingdrawings, which show the preferred embodiments. The essentialcharacteristics are summarized in the claims.

In the drawings, Fig. 1 is a substantially central vertical crosssectional view of the entire mechanism; F.g. 2 is a cross sectionaldetail view taken along the line 2-2 on Fig. 1; Fig. 3 is a sectionalplan view taken substantially along the line 3-3 on Fig. 1; Fig. 4 is adetail sectional bottom plan view through a portion of the drivingmechanism, the section being taken substantially along the line 4--4 onFig. 1; Fig. 5 is a detail sectional view taken substantially along theline 5--5 on Fig. 1; Fig. 6 is a bottom sectional plan view of the baseand the driving mechanism between the drier and washing elements asindicated by the line 6-6 on Fig. 1; Fig. '7 is a fragmentary sectionalView similar to Fig. 1 but showing theA power driving unit removed fromthe machine; Fig. 8 is an enlarged fragmentary central vertical crosssectional view of the detachable power unit; Fig. 9 is an enlargedfragmentary sectional view of the dolly support and driving mechanismtaken along the line 9-9 on Fig. 3, and Fig. 10 is a fragmentaryperspective view of one of the dolly parts.

Referring again to the drawings, 1 indicates the base for the variousmechanisms comprising the invention. This base supports; on its topside, a suitable casing 2 forming a washing chamber 3 and drying chamber4, the chambers being separated by a transverse substantially verticalpartition 5 dividing the casing 2. As shown in Fig. 3 particularly, theWashing chamber is the larger of the two, and in this chamber andsupported on a tubular post 6 is a dolly 7, the novel features of whichwill'be hereinafter more fully described. The chamber 4 containsthedrier drum 10 having suitably perforated or reticulated walls, the drierbeing supported on a shaft 11 extending from the base.

Detachably secured to the casing 2 is a power driving unit, indicatedgenerally at l2, parts of which form a removable cover for the drierdrum chamber 4. This unit includes a motor 13 having a depending driveshaft 14, the drive shaft carrying at its lower end, the driving element15 of an air-couple or clutch, the detailed characteristics of whichwill be hereinafter more fully described. The driven element 16 of thisair couple is propelled solely by air drag, both air coupling elementshaving suitable vanes disposed in fairly close proximity to each other,as shown in Fig. 8. A portion of the driven element 16 sets into the topof the drum to center and drive the latter.

The drier drum 10 is arranged to drive the agitator or dolly 7, the drumdriving its supporting shaft 11 to which, at its lower end, is a pinion20. The pinion 20 is part of a reduction gearing including also arelatively large spur gear 21 supported in the base, which gear 21 hassecured thereto a pitman 22, the pitman being also connected with an arm23 fast on the lower end of a suitable shaft 24 which, as will behereinafter more fully described, is drivingly coupled with the dolly. A

The base is constructed and arranged to form a substantial support forthe drier and dolly mechanisms generally described above, and also toform a sealed oil casing and housingfor the reduction gearing and pitmanmechanism. As shown, there is an outer pressed metal base forming shellhaving substantially vertical but inwardly inclined walls at 30 and ahorizontal wall at 31 extending inwardly a short distance from thesubstantially vertical walls, the inner margins of the top wall beingfianged downwardly as at 32. The walls 30 may be flanged outwardly attheir bottom margins and reinforced by a suitable doubled strip of sheetmetal indicated at 30 forming a finishing bead. Seated in theopening-formed by the inner marginal flanges 32 of the base member abovedescribed, is a sheet metal oil casing member having vertical walls at33 and a bottom wall at 34. The walls 33 are flanged outwardly at 35 tooverlie the margins of the horizontal portions 31 as a. verticalsupport. Surmounting the base and oil casing members just described, isa relatively stiff, substantially horizontal plate 40, the marginaledges of which lie above the superimposed parts of the flanges 35 andthe wall 31. The casing and base members may be secured together as bysuitable screws 36, there being a sealing gasket of suitable material at37, clamped between the outer edges of the plate 40 and the flanges 35to prevent leakage of oil from the casing.

The supports for the shafts 1l and 24 and associated parts, whichrespectively carry the drier drum and drive the dolly will now bedescribed. The main supports comprise, as shown, suitable castings andtubular bearing members rigidly supported on the top plate 40.

For supporting the shaft 1l, there is a tubular bracket 45, throughwhich the shaft l1 extends, this casting having an outwardly extendingflange 46 intermediately of its ends, resting on and secured to theplate 40, the plate having a suitable opening 40' closely receiving anannular shoulder 47 on the casting to hold the casting against lateraldisplacement. The shaft 11 is shown as threaded at its lower end toreceive the pinion 20, which may be held on the shaft by a suitable nut48. Downward thrust on the shaft l1 is arranged to be taken by agenerally U -shaped strap member, shown in detail in Fig. 2 at 49, whichstrap has oppositely extending top portions underlying the plate 40 andthe flanges 46 of the casting. To decrease friction, a suitable ball 53may be interposed between the strap 49 and the end of the shaft, boththese last mentioned elements being suitably recessed to retain the ballin place. It is desirable to isolate the casting 45 from water withinthe chamber 4, and for this purpose the casting may be covered by aprotecting cap 55 which, as shown, closely embraces the shaft at itsupper end and above the casting 45, and which is flanged outwardly as at56 at its lower end, the flanges lying between a suitable attaching ring51 and an annular gasket 57, which latter is interposed between the ringand the bottom of the casing.

Two sets of securing screws are preferably employed to hold theoverlying parts just described rigidly together. As shown, there arescrews 50 which pass from and through the attaching ring 51 tothelowermost member to be secured, namely the strap 49, as shown in Fig.2, and the plate 40, as shown in Fig. 1. Additional, shorter,

screws 50' (see Fig. 1, one being shown), merel hold the casting 45 ontothe plate 40.

The casting provides spaced running fit bearing portions for the shaft11 these being separated by the cored recess 45' into which extends anoil wick 45", the wick passing through a suitable hole (not shown)formed in the casting 45 to allow the wick to extend to the sumpprovided by the oil casing 33-34.

'I'he preferred construction of the drying drum 10 is as follows. Themain body member 60 of the drum may comprise simply a single piece ofsheet metal suitably perforated at 61 and curled up and joined in anysuitable way into a cylinder. At the top, the member is reinforced by anannular sheet metal rim member 62 which, as shown, is frusta-conical andopen at the top. The rim may be curled over as at 63 for engagement withthe driving portion of the driven element 16 of the air couple.

The bottom of the drum, as shown, is formed of a sheet metal disc 65,flanged at 66, for attachment to the cylinder 60. The disc has a raisedcentral substantially cylindrical portion 67 depressed as at 68 formingan annular rib 68' which is uppermost. The depressed portion 68 formsone element of the safety slip coupling 1'7, provided mainly to avoiddamage to the machine in the event that the dolly is abruptly stopped,as by becoming jammed by too large or heavy a load. 'I'he other partscomprise a centrally perforated metal cup 70 fast on the shaft, theupstanding rim '70 of which confines a friction dsc 71 of suitablematerial, such as fiber or cork for example. The rib 68 of the disc 68may be engaged by a spring metal disc 73 pressed downwardly by asuitable nut 74 threaded to the top of the shaft ll'to yieldingly forcethe slip coupling parts toward each other and thereby, under normalconditions, drvingly couple the drum to the shaft 11.

'Ihe supporting arrangement for the agitator or dolly and its drivingshaft is as follows: Seated on the top side of the plate 40 is a flangedtubular sheet metal member 80, the flanges lying between the bottom'ofthe casing 2 and the plate. The tubular member has its smallest portion8l embracing the bottom end of a substantially cylindrical hollow post,heretofore referred to as 6. The post and member 80 may be securedtogether in any suitable way as by welding or soldering. The shaft 24extends for the most part. freely through the tubular post 6 but may, ofcourse, have any suitable guiding bearing arrangements within it. Asshown, there is a bushing bearing at 82 secured in the end of the postas by solder for example, and in which the shaft 24 has a running fit.The shaft is vertically supported and guided at its lower end by abushing bearing 85 seated in a casting 86 which is flanged as at 87 tounderlie the plate 40 at a suitable opening therein, in which thecasting is shouldered as at 87'. The shaft is reduced as at 24' toprovide a shoulder against the top' of the bushing 85, and the pitmanarm 23 may be suitably keyed to this reduced portion of the shaft, as at88 and secured by a suitable stud 89.

For detachably securing the dolly 7 to the shaft, the dolly may have atits upper end a socket member 90 having a slid`ng key connection at 91with the upper end of the shaft 24, permitting the dolly to be easilyslipped off its driving shaft and removed from the casing 3.

The manner in which the various parts 80, 86, etc. are secured to eachother and to the supporti'ng plate 40 is substantially the same as thatl fully described above with relation to the bracket 45 and associatedparts, hence this needs no detailed description.

The preferred construction of the dolly is, in detail, as follows: Thecentral supporting body of the dolly comprises a metal tube 94 whichlies in generally spaced embracing relation to the upstanding tube 6,except that, at the lower end of .the tube 94, the tube bears on and isguidingly supported by the exterior cylindrical surface of the reducedportion 81 of the hollow bracket 80, previously described. Lateralsupport for the upper end of the tube 94 is afforded by reason of thesocket member 90, which may, for example, be soldered or welded into theupper end of the tubo 94 so as to be rigid therewith. The tube 94. itwill be seen, is, by the arrangement above described, easily removablefrom the xed tube 6. this also affordng a suitable means fordisconnecting the dolly from its driving shaft 24 when desired.Moreover, the entrance of water into the interior of the tube 6 iseffectively prevented at all times.

The dolly or agitator blades are preferably formed of molded rubber orother similar substance, indicated at 100. It is not entirely essentialthat this substance be resilient and yielding, though this is preferred.I may use such a substance as a phenol condensation product instead.

The blades are individually secured in xed position, but detachable forrepairs and replacement on the tube 94. As shown in Figs. 3 and 9particularly, each blade has a generally crotchlike base at 101, fittingthe tube 94, and an out standing flexible arm at 102 corrugated, preferably vertically, at its opposite sides at 103 for rubbing action on thematerials to be cleansed. Within the crotch-like bases and extendingfrom the top to the bottom of the blades, preferably molded in place,are metallic reinforcing strips 105. These reinforce strips extend intoreduced end portions of the blades at the top and bottom, as at 105', toform elements for rigidly associating the blades with the tube. Thereinforcing members also have openings at 106 receiving the rubber orother material when molded onto the strips to more rmly hold thismaterial. Adjacent the tube 94, the strips 105 have key formations 107arranged to enter longitudinally spaced aligned openings or slots in thetube substantially tting the keys.

As a further means for securely holding the blades in place on the tube,I providesattachingstrips 108, the form of which is best shown in Fig.10. This gure shows a longitudinally folded sheet metal body havingoppositely directed flanges at 109 and end extensions 108 lying beyondthe anges at both ends. The doubled edge of each strip 108 rests againstthe tube between the adjacent portions of the base members 101 of eachtwo adjacent blades, the flanges 109 overlying the margins of each base101, as is apparent from Fig. 3. It will be seen that the dolly membersabove described may be easily assembled onto the tube and held in placeby any suitable arrangement embracing the upper and lower ends of thereinforcing strips 105 and the attaching members 108. As shown, there isa ring 109 having a diverging upstanding annular flange embracing thelower ends 105 and 108 of the reinforcing members and stripsrespectively, as well as the reduced end portions of the blade material100. This flanged ring 105 may be secured to the tube 94 in any suitablemanner as by welding or soldering the ring to the tube. The upperprojecting ends, 105' and 108', and the end portions of the bladematerial, are likewise embraced by depending anges on a suitable cap 110which is threaded as at 111 to the socket member 90. It

member 90 holding the assembled parts securely in place.

The active portions of the blades being, as previously mentioned,vertically corrugated, these act on the materials being cleansed toforcibly rub the materials while the rapid oscillation of the bladescauses the materials to be thrown to and fro with considerable force. Avery desirable washing action is afforded by reason of the resilientcharacter of the blades, when made of soft rubber, for example, thisbeing a slapping action which has been found to wash the materials verythoroughly, assisted, of course, by the rubbing action of thecorrugations.

Referring now to the top of the casing 2, it will be seen that the sheetmetal walls are rigidly braced and surmounted by an open top frame 125,preferably a single casting, arranged to be rigidly associated with thecasing walls as by virtue of depending flanges 126, continuouslyembracing the marginal edges of the casing Walls, as suggested inFig. 1. The frame extends outwardly as at 127 to provide suitablehandholds for moving the machine from place to place, as desired.Suitable openings at 130 and 131 lead through the frame into theinterior spaces or chambers 3 and 4 respectively. These openings should,of course, be normally covered during the operation of the machine. Theopening has a suitable sheet metal cover at 132, and the other opening131 is effectively closed by sheet metal housing and supporting membersforming parts of the detachable power unit 12, previously described in ageneral way. This power unit and associated parts will now be describedin detail.

Referring to Figs. 1 and 8, it will be seen that the motor casingsurmounts a separate sheet metal annular shell 141 having generallyconical side walls 142 which terminate in a horizontal shoulderformation at 143, extending beyond which, toward the drum, is asubstantially cylindrical rim flange 144 arranged to enter the opening131 a considerable distance.

Beneath the shoulder formation 143 is a suitable resilient ring 145 ofmaterial, such as rubber, forming the actual support for the shell 141.

The shell'has suitable sheet metal bracket4 formations at 148 at itsopposite sides which extend upwardly over the top of the shell, oppositeend portions of each of these bracket formations being bent up as at150Y to support suitable handles 151 by which the power unit may beremoved and easily handled. The bracket formations 148, further, extenddownwardlyand then outwardly at 152 to form circumferentially slottedears, the nature of the slots being shown at 153, Fig. 4. The ears 152are arranged to underlie suitable headed securing members when the powerunit is turned, as will be obvious from Fig. 4, the headed members beingsecured to the frame 125, as shown in Fig. 1. One member, 155, maycomprise simply a screw with a suitable head for 'of the opposite ear.

engaging the top side of one of the ears and the other member maycomprise a stud 156 with;

neath it. This releasable head is provided simply to prevent accidentalremoval of the power unit, and to allow the unit to be easily turned todetach and remove it when desired.

To provide a suitable resilient support for the motor, not shown butlocated in the casing 140, the motor has a substantially fiat horizontalsheet metal base plate 160, to which, it may be assumed, the motor isattached in any suitable manner. Between an outstanding flange 140 andthe uppermost portion of the shell 141, there is a substantially fiatannular yielding support 161 for the motor base plate. This yieldingsupport is clamped between a metal ring 162 and the flange 140', as bymeans of any suitable arrangement of bolts or like devices (not shown),the uppermost portion of the shell 141 lying between the ring 162 andthe yielding support. Beneath the base plate, there is provided anannular sheet metal disc 163 which at its outer margin is depressed sothat the superimposed and spaced portions of the member 163 and plate160 hold the inner marginal edges of the yielding support between them.

Below the plate 160 and attached thereto is a hollow bearing bracket 170for the motor shaft 14, the bracket being flanged as at 172 forattachment to the underside of the base plate 160 and having a reducedneck at 174. The neck forms a shoulder for an inner bearing race member175, held on as by a suitable nut 176. This bearing race member is partof an ordinary annular bearing, including balls 177 and an outer racemember 178, which latter carries the outer or driven element 16 of theair-couple, the preferred arrangement of which will now be described.

The air-couple member I16 comprises an annular base or body 180, formedpreferably of a phenol condensation product or like comparatively lightbut strong substance adapted to be molded or cast. This base 180 hasupstanding vanes 181, preferably arranged as shown in Fig. 4 incooperative relation to vanes on the driving element 15 of theair-couple. The vanes 181 at the top are slightly recessed as at 181 toreceive a sheet metal disc 182 preferably of spring steel which suspendsthe element 16 from the outer bearing race member 178, above described.The disc is set into the recess 181' and held in any suitable manner asby a series of screws 183 entering openings in the disc and the variousvanes or blades 181. To secure the disc 182 to the bearing race member178, I propose to provide substantially complementary sheet metalmembers 185 having superimposed flanges at 186 riveted or otherwisesuitably secured to the disc 182 and formed to embrace the bearingelements and lie close to the bearing bracket 170 at their innermarginal edges. Suitable means, such as felt packing, may be interposedbetween the members 185 and the bearing parts to retain suitablelubricating grease in the bearing, and protect the bearing parts frommoisture.

A suitable drum driving surface may be formed at 190 on the body portion180 of the driven air-couple element 16 which, in the event this body isformed of a phenol condensation product, is sufficient for frictionalcontact with the interior of the rim 62 of the drum, to drive thelatter. However, I may also provide a rubber ring 191 retained on thesurface 190 against a shoulder 192 on the body in any suitable way. Suchrubber ring forms an abutment between the body and the bead 63 of thedrum, by reason of which, when the'power unit is secured in place, thespring disc 182 is sprung slightly upwardly from its normal position,thereby securing a firm driving contact between the aircouple element 16and the drum.

The preferred construction of the fan or driving element 15 of theair-couple is obvious from Figs. 4 and 8, but it may be explained thatthis fan may comprise substantially Isolid disc and hub formations 195and 196 respectively, which are integral with the fan blades 197. Thefan, f in case this is also made of a phenol condensation product orsimilar substance, may have a metallic ferrule 198 embedded in it forsuitable 100 threaded attachment at 199 with the motor shaft.

The fan 15, it will be seen, gets its air from within the drum through acover plate or ring 200 on the bottom of the body 180 of the element 16,which plate is centrally apertured at 201, the aperture being covered bya reticulated guard 202, such, for example, as a metal screen disc,suitably soldered or attached to the plate 200. For attaching the plateto the body member 180, suitable ferrules may be embedded as 1 at 203into this body to receive screws 204, with their heads underhanging thecover plate.

From the above description, it will be seen that I have provided anumber of highly efficient and advantageously arranged mechanismsforming a 1 strikingly efficient portable washing and drying unit. 'I'headvantages of the various mechanisms forming this unit have beenpreviously set forth, but the following may be noted with respect to themechanism as a whole.

The washing chamber is easily charged with material to be cleanedthrough the frame opening 130 and the casing filled with an adequatequantity of water or other cleansing liquid and a suitable detergent ifdesired for the materials to be cleansed, and the washing operationstarted simply by energizing the motor, assuming the power unit is inplace, as shown. Motor and driving fan speed is 9000 R. P. M.; drivenfan and dryer speed is 900 R. P. M. Assuming the motor is of adequatecapacity and operates say with a rotational speed of approximately 9000R. P. M., the dolly will be operated at about 90 oscillations perminute, thoroughly agitating the clothes as well as imparting thereto arubbing and placed in the centrifugal drying drum, the

power u nit being rst, of course, removed. The power unit may now bereplaced in the position shown in Fig. 1 and started, and by virtue ofthe air couple connection, the drum will now be rotated at approximately900 R. P. M., resulting in quickly driving most of the water therefrom.An important advantage of the arrangement is that washing and drying maybe carried out slmaterials in the drum will be ready for hangingup tofully dry. when the washing operation is completed.
